QUANTUM SERIES 2026 The complete learning path, from a single qubit to Grover’s algorithm.
This is the index to the Techucation Quantum Series: a sequence of hands-on posts that build quantum computing from the ground up. Each one stands on its own, but together they form a single arc, from what a qubit actually is, through the rules that make quantum mechanics strange, to the algorithms that turn those rules into a real speedup. The order below is a learning path from first principles to algorithms, not the order the posts were written.

Foundational Pre-reading: The Math Behind the Phase
The geometric bridge from qubit statevectors to gates: where |0⟨, |1⟨, |+⟨ and |−⟨ sit, how X and Z rotate them, and how to verify the result in Qiskit.
Moving beyond single qubits: tensor products, product states vs entangled states, Schmidt decomposition, CNOT as the universal entanglement generator, the four Bell states, Bell basis decoding, and why the single-qubit Bloch vector collapses.
Scaling to n-qubit Boolean functions: provable exponential query separation, phase kickback, the four canonical oracles, and Qiskit 2.x implementation.
Putting entanglement into action: an interactive simulator where quantum correlation violates Bell’s inequality, beats the classical 75 percent ceiling, and reaches the Tsirelson bound (85.4%).
